Yes, more people are living in mobile homes, caravans ( a travel trailer is still a caravan and all the pros and cons that come with them), vans, cars than ever before.
Govt owned and run RV parks would be a good idea.
Having 'lived' 'van life' for 2 years now on Youtube thru the eyes and lives of those doing it...some for fun, others out of necessity...I believe one problem the van lifers have is the cost of staying in said parks to get access to water, electricity, showers, toilets...in safety.
California is very wealthy with a huge tax surplus, the surplus needs to go towards helping the homeless people in California, it is a crisis right now with over 60,000 homeless people on the streets of Los Angeles alone. RV parks are a great idea to help the homeless, and Santa Clarita, and Acton, etc, have some very nice locations for RV and travel trailer parks.
And because California is wealthy, and because the USA is wealthy, the people in the RV parks can have doctors, and pharmacies, etc, and swimming pools, and tennis courts, etc. And they can have stores to buy groceries, and they can have 7 Eleven convenience stores, etc.
It is also good to have activities for the people, so they can socialize and so that they can have a sense of community, and so that they can have a higher quality of life. When I lived in an RV park I used to cook for everyone, and I had a blender and I made margaritas for the people, etc. I had 3 barbecue grills and I made tacos and burritos, and chicken, etc, for the people. The people said that hanging out with me at my RV space was like living in Malibu. We can elevate the whole experience by having social activities for the people, such as having cook outs when the people can all eat together, and they can drink beer and margaritas, etc. During the Great Depression they used to have dances for the people in the tent cities, and that kind of stuff is good.
Also, many of the homeless people are mentally ill and have other medical issues, so the people need doctors and psychiatrists and pharmacies, etc. We are wealthy, and we can provide services for the people here. By having mental health services and other medical services for the people then we can make it much nicer for the people.
There can be workers to keep the landscaping nice, etc. The RV parks can be nice.
Then, for the alcoholics and drug addicts we can have drug treatment camps in Acton, and in Lake Hughes, where they can get help and where they can get started on the 12 step program, etc.
Then of course we can build the Santorini, Greece, style apartments with swimming pools and tennis courts, we can make it very high density like in Greece, so many apartments can fit into a small amount of land, while at the same time they can be beautiful with charm like in Greece.
Salute,
